title: Generation and characterization of heritable reciprocal translocations in mice.
abstract: Reciprocal translocations have provided crucial tools for the localization of genes associated with a variety of human cancers and hereditary diseases. Although heritable translocations are relatively rare in humans, they can be easily induced in mice through exposure of male germ cells at specific spermatogenic stages to different types of radiation and chemicals. Mutagenesis schemes that produce translocations at high frequencies in the progeny of treated males are summarized, and the use of these valuable mutations for analyzing developmental consequences of partial aneuploidy, for identification of mutant genes, and for other purposes is reviewed. Preliminary studies of a large collection of translocation mutants, including several stocks that display dominantly or recessively inherited phenotypes caused by the disruption of critical genes are described. These combined studies demonstrate that several mutagenesis protocols can be used to generate easily mapped, novel mouse mutations with high efficiency and highlight the unique value of reciprocal translocations as tools for gaining access to the biological functions of mammalian genes.
